ASTM A671 Pipe

What is ASTM A671 pipe, and what are its key features and specifications?

ASTM A671 Pipe is a specification established by the American Society for Testing and Materials (ASTM) that outlines the requirements for electric-fusion-welded steel pipe suitable for atmospheric and lower temperatures. This type of pipe is commonly used in various industries such as oil and gas, petrochemical, and power generation.

One of the key features of ASTM A671 pipe is its ability to withstand lower temperatures, making it suitable for applications where temperature fluctuations occur. Additionally, these pipes are designed to have good weldability, ensuring strong and durable joints.

Regarding specifications, ASTM A671 pipe covers different grades and classes, each with specific mechanical properties and chemical compositions. The grades range from CA55 to CA102, with varying tensile strength and yield strength requirements. The classes, denoted as Class 10, Class 11, Class 12, Class 13, Class 20, Class 21, Class 22, and Class 23, indicate different heat treatment procedures and impact test temperatures.

What are the main applications and industries that utilize ASTM A671 pipes?

ASTM A671 pipes have extensive use in various applications and industries due to their specific characteristics and suitability for various operating conditions. The oil and gas sector is one of the primary industries that utilize ASTM A671 pipes. These pipes are commonly employed for transporting oil, gas, and other hydrocarbon fluids from production sites to refineries or distribution points.

Another significant application is in the petrochemical industry, where ASTM A671 pipes convey chemicals, gases, and other corrosive substances. The pipes' corrosion-resistant properties and ability to withstand lower temperatures make them suitable for handling a variety of corrosive media encountered in petrochemical processes.

ASTM A671 pipes are widely used in power generation facilities, particularly in thermal power plants. They are used to construct piping systems that transport steam and water, which is crucial in power generation through boilers and heat exchangers.

ASTM A671 pipes also find applications in infrastructure projects, including water supply and sewage systems. Thanks to their durability, strength, and resistance to environmental factors, these pipes can be used for transporting water, wastewater, and other fluids.

Rolling and welding

Firstly, the carbon steel strips are made to gone through various quality checks and are trimmed at edges. They are then fed to the tubes mill by carbon steel pipe manufacturers in India. The strips pass through the number of rollers as per the required size. In the tubes-mill, the strip is gradually converted into the tubular shape. The fitted welding machine is then used to weld trim edges of the strip using TIG welding process. The scraps and inside weld bead are removed instantaneously by the Tibo machine. In this way, rolled pipes and tubes are formed.

The cleaning and heating phase

The rolled High Pressure Seamless Pipes thus manufactured are cut to the required lengths depending upon the industrial demand. These stainless pipes and tubes are then subjected to cleaning to remove the dirt. Further, a heat treatment is given to these rolled pipes and tubes to remove the stresses that may occur due to welding and formation processes. Heat treatment is given on the continuously rolling hearth furnace. The furnace is fitted with temperature recorders and controllers. After the heat treatment process, the SS tubes and pipes are straightened and subjected to pickling for removing scales from the surface.

Cold- drawing process

In some cases, the required size may not be obtained from the mill directly. Then, the cold operation process can be used to obtain the desired size. In cold drawing process, the tubes or pipes are coated with oxalic and soap solution. This solution acts as a lubricant to reduce friction while cold drawing operation. In the cold drawing process, the tube or pipe is drawn over the bench using Die plugs.

Finishing process

The drawn-out tube or alloy pipe is then subjected to cleaning, heat treatment, pickling and straightening. The computerized ink jet marking machine is used to do the marking on the finished pipes or tubes. The pipe or tube is marked with grade of material, size, heat number and the stamp of third party inspection before passing on to carbon steel pipe exporters. The stainless tubes or pipes thus produced will undergo certain testing and quality checks. This process is followed by proper packing and dispatch. There are numerous numbers of carbon steel pipe applications, these pipes and tubes are used thereafter for.
